Companies ranging from IBM to Novell are dramatically expanding Linux training and development. Certification will be a key part of this trend, and support is growing for an industry-wide Linux certification program. Most companies want a vendor-neutral certification initiative, and the Linux Professional Institute (LPI) is the leading effort in this direction. As more corporations adopt Linux as the networking backbone for their IT systems, the demand for certified technicians will become even greater.LPI Linux Certification in a Nutshell prepares system administrators for the basic LPI General Linux 101 exam and the more advanced 102 exam, and includes information on objectives and test suggestions. It also provides readers who aren't planning to take the exam with an excellent understanding of the targeted Linux concepts and functions.The book is divided into two parts, one for each of the LPI exams. Each part features a summary of the exam, a Highlighter's Index, labs, suggested exercises, and practice exams to help you pass the LPI exams with flying colors.Part I covers the General Linux 101 Exam:

GNU and Unix commands

Devices, Linux filesystems, and the filesystem hierarchy standard

Boot, initialization, shutdown and run levels

Documentation

Administrative tasks

Part II covers the General Linux 102 Exam:

Linux installation and package management

The Linux kernel

Text editing, processing, and printing

Shells, scripting, programming, and compiling

X-Windows

Networking fundamentals

Network services

Security

For those preparing to take the LPI Linux Certification Exams, this book will prove to be invaluable in its scope and breadth. Linux newbies will also find this book useful for learning more about how to use their Linux system.Jeffrey Dean is a Red Hat Certified Engineer (RHCE) with professional experience in IT management and training delivery.

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of LPI Linux Certification in a Nutshell is a Texas longhorn cow. Christopher Columbus originally brought cattle to the New World from Spain. Descendants of these animals mated with English cows, and the offspring gradually evolved into the breed we know today.Unfortunately, this animal was once on the verge of extinction. In the 1800s and the early 1900s, tallow was a valued resource, as it is a key ingredient in candles and soaps. Animal fat is a major component of tallow, and the naturally lean longhorn didn't have enough of it to be considered useful in making a fat-based concoction. As a result, the longhorn was cross-bred with cattle who had more fat, so cattle ranchers would be assured of a larger financial profit in the tallow industry. Purebred Texas longhorns were being phased out. However, in 1927, the U.S. Congress decided to step in, and formed a government herd of this breed, to save them from disappearing altogether. Very few purebred Texas longhorns were found, but Congress did manage to round up 27 animals, which were placed in a reserve area in Oklahoma. Today, the Texas longhorn is enjoying a rebirth of sorts, with numbers in the U.S. of up to 100,000.

This book is informative and well written. However, it is getting very old, and therefore it is NOT a good source if you are going to take the LPI Linux exam! If you go to the LPI.org site, you will see that the objectives for passing (for instance) the 101 test have changed a lot since the book was written. Only two objectives out of five are essentially unchanged (GNU, Unix Commands, filters, and the chapter on Devices, Linux Filesystems, Filesystem Hierarchy Standard). However, 60% of the test has changed and now include The X Windows system, Linux installation and package management, and hardware and architecture. These were previously part of the 102 test.

Another problem with the book is the large number of typos in the command examples, and that as the chapters have been moved around between the 101 and 102 sections, several test and review questions have remained in the wrong chapters. There is a large list on the errata page, and I have found many more.

It could be that I am using a non-standard distro (Mandrake), but many of the commands listed in the book have changed. For instance "top -q" does not work, there is no such parameter. "rm -d" is obsolete on many distros, you should use "rm -r" instead.

However, the greatest problem with this book is that it no longer covers what is part of the LPI exams. I think O'Reilly should add a "deprecated" warning to this book on the homepage, as you would likely fail if you went to the test prepared with only this book. I had been studying the book for a couple of weeks until I felt rather sure I was going to pass the test. When I booked a time to take the test, I noticed I had to check wether to take the Debian or RPM version of the test. I didn't think much of it until there was three days left before the test. I started thinking, hang on, isn't RPM part of exam 102, why did I have to check that for 101? I decided to go the LPI homepage where I got quite a shock. Stupid of me not to do it earlier, but still. I now have one day left... but I think it will work. Google is my friend.

Summary - good but dated book if you want to learn Linux. As a guide to pass the LPI test it is terrible.

This book has some very good qualities, it is informative and I have learned a lot from it. However, if you don't have good eye sight and have a hard time reading italics it is not so good. It needs to be double spaced and raise the font size for easier readability. It also needs to be updated, to reflect linux in it's present state as well as staying within the context of the exam. I am glad it is more RedHat based, and errors or not it is worth reading. But please, make it easier for people who wear glasses to read.

Good book ,though it is a hard content so newbies will be having difficulties but in general it is a good reference to pass both exam and finish daily tasks ,but updates are required to pass the new version of the LPI

One more comment that I find that there are some differences between the English version and the Chinese version (URL: http://www.oreilly.com.tw/chinese/linux/lpi_linux.html). Although the Chinese one does not contain the new Level-1 objectives, it looks a little bit better than an outdated English version. I highly recommend O'reilly to take some actions about that.

It's a good reference book for all candidates for LPIC Level 1. Although the objectives of LPIC is redefined that the structure of content becomes unuseful, the content is full of information for the examination. Also, it's a good guide for preparing LPIC examination.

I also promote the style of this examination guide that including highlights, mock exam and exercises. I'm seldom got similar books at bookshops.

I suggest O'reilly may publish an updated version. Or post a new reading guide for new objectives on web. Also, errata list may keep update as possible that too many unconfirmed erratas (either it's a real errate or not) may lead some candidates to be failed in LPIC exam.

On the whole it's a good book but lpi certs are very much a moving target - the current publication does not include topics which are now current in the Level 1 exams such as 'notifying system users' and 'setting the hardware clock'.

The long list of 'unconfirmed' errors are well and truly confirmed by readers - the fact that the publisher has not acknowledged them seems a little churlish. Why aren't these mistakes acknowledged? Does the publisher think they are anomalies ???!

I would recommend this book though, as there really is little else to go on for these exams. It is a good book but READ THE ERRATA BEFORE PURCHASING!

This book is certainly a useful summary of the topics required for the LPI 101 and 102 exams. The material corresponds reasonably well with the actual tests (at least the ones I took). That said, there are quite a few shortcomings.

First, there are too many errors and typos. Just as an example, on page 348: script sourcing is described as execution in one script comment, example 2-6 claims to show a system-wide .bashrc file (with the leading dot), and example 2-7 claims to source the /etc/bashrc, although it does not. Not every page has 3 errors on it, of course, but generally the book does not make an impression of being proofread too carefully.

Second problem is that the author does not seem to have much experience with any other ditribution than RedHat. Almost all examples are RH-specific, and sometimes the description is valid only for the RH system. E.g., the pump command, whois being a link to fwhois, the Xsetup_0 configuration file, or usage of the RH-modified font server ("unix:/-1") in XF86Config. The exams are truly distribution-neutral, the book is not.

The last comment concerns my impression that the author ran out of energy while writing the book. The chapters on 101 exam are much better than those on 102 exam. The last few chapters on networking and security are particularly weak. E.g., the description of non-routable networks (10.* and friends) or the DNS service is not sufficient to answer the test questions. The highlighter's index for 102 exam is also much worse than that for the 101 exam. E.g., the rpm and dpkg summary is only six lines long while these are the most important test topics of the 102 exam (as is also indicated by their high weights).

In summary, I would somewhat reluctantly recommend this book to those taking the LPI test - despite all the problems, it represents a useful and fairly complete overview. However, don't rely on it too much and check the manpages and HOWTOs often.

I used LPI Linux in a nutshell to help me achieve LPI Level 1 Certification in 2 months. The author is quite knowledgeable and his explanations made it a good read. I really enjoyed the format as it covered each objective and the layout was like a tutorial. It will be a good reference book aside my other Oreilly books.

I hope Oreilly will have another LPI certification book for level 2 soon. Oreilly has a good thing going here with their "nutshell books"
